Adrianne Haslet-Davis, a dance instructor and professional ballroom dancer who lost her foot in the attack, will appear as a special guest.

While dramatic storylines are never hard to find during ABC's hit competitive reality series "Dancing with the Stars," tonight's special guest will certainly be a highlight among the show's 16 seasons.

Adrianne Haslet-Davis, a 32-year-old dance instructor and professional ballroom dancer, was tragically injured during the Boston bombings earlier this month. As a result of her wounds, her leg was amputated below the knee. Nevertheless, she is determined to return the ballroom, something "DWTS" producers were happy to oblige with a special invite.

“I think the show is just phenomenal,” she told Extra after sharing her disbelief at the invitation to appear. “Obviously I am a fan of anybody that can teach anyone how to dance, being a teacher myself, and I think it is wonderful to see people’s journey.”

While Adrianne has remained tight-lipped as to what we can expect, "DWTS" pro Derek Hough told TODAY.com that her participation on the program was incredibly moving.

"Thank goodness we have amazing technology now where she will be able to walk, she will be able to walk again in a different way," he said. "I think that ... tragedies like that, which are so unfortunate, you can find the brightest light as well. I just pray and hope for her that she finds that bright light and turns it into something that's special in her life. ... I just hope for the best, that she stays in that positive place."

"We want to be entirely forthright with everyone who makes a donation. Your dollars will be put to work," the site states. "Adrianne and Adam are going through near-unimaginable things right now, and they could really use our continued support. They’ve also been clear about intending to share some of the proceeds amongst other affected. Thank you to everyone who has contributed; it means the world to us. Thank you."
